Benson, 29, who rushed for more than 1,000 yards the past three seasons in Cincinnati, could provide a good power complement to speedy Darren McFadden.

With McFadden’s injury history—he missed nine games last season because of a foot injury—the Raiders need a good insurance policy after losing backup Michael Bush in free agency to the Chicago Bears. Oakland’s current backups are unproven Mike Goodson and Taiwan Jones.

Earlier in the week, ESPN.com reported the Raiders had interest in Benson but that “salary cap and money issues” were obstacles to completing a deal.
